I have a 20amp circuit breaker with 15 amp receptacles and light switches on #12 wire with a load of 1700, is this allowable? If not, and I change to a 15 amp circuit breaker, is the 1440 watt safety load in the code or is it a non-code safety suggestion?

You're fine. 1920 watts is 80% of 2400 watts(80% of 20 amps @ 120 volts)If you have something serious, maybe add circuit.

Thank You, I've had all sorts of answers to this question. I am mainly concerned with not having to change the 15amp receptacles and switches. Birdseye
